Embodiment Construction
[0036] Below, refer to Figure 1 to Figure 4 , a tire pressure monitoring system for a vehicle according to an embodiment of the present invention will be described. A tire pressure monitoring system (TPMS: Tire Pressure Monitoring System) is installed on the vehicle, and the tire pressure monitoring system detects the air pressure and / or temperature of the tire and monitors whether the air pressure and / or temperature are abnormal.
[0037] Such as figure 1 As shown, each tire 2 (4 in total) of the vehicle 1 is provided with a tire electronic valve 3 , the tire electronic valve 3 has an air inlet, and sends wireless signals to the air pressure and temperature of the tire 2 . An electronic valve control unit 31 for controlling the operation of the tire electronic valve 3 is mounted on the tire electronic valve 3 . Connected to the electronic valve control unit 31 is a UHF transmitter 32 that transmits a detection signal Stp including the air pressure and temperature of the ti...

The invention provides a communication method, a communication system, a sending device, a receiving device and a tire pressure monitoring system which can raise sending information integrity and restrain data increase. The communication method transmits a detection signal including a valve ID, which is a fixed data string, and detection information, which is a variable data string, performs error detection on the received detection signal, and uses the detection information when there is no error. The communication method generates third data corresponding to the detection information in accordance with a predetermined rule to increase redundancy of the detection information, generates computed data by performing an exclusive disjunction logic operation with the valve ID and data including the detection information and the third data, transmits the detection signal that includes the computed data, receives the detection signal, restores the detection information and the third data by performing an exclusive disjunction logical operation with the received detection signal and the computed data, and determines whether the detection information conforms to the third data.
Description
technical field [0001] The present invention relates to a communication method, a communication system, a transmitting device, a receiving device, and a tire pressure monitoring system capable of improving the integrity of transmitted information and suppressing the increase of transmitted data. Background technique [0002] In recent years, a tire pressure monitoring system (TPMS: Tire Pressure Monitoring System) for monitoring tire pressure has been installed on a vehicle. The tire pressure monitoring system is a system that obtains tire pressure and / or temperature from electronic tire valves installed on the tires of the vehicle through wireless communication while the vehicle is running, and monitors whether the tire pressure and / or temperature are abnormal. [0003] The tire electronic valve of the tire pressure monitoring system transmits wireless signals including detection information such as air pressure and / or temperature, and an ID code for identifying the vehicle...
